The cumulative effect of these drivers has resulted in a net loss of over 3.40 million hectares of tree cover. This figure represents the balance after accounting for the area of tree cover gained against the total loss. The disturbances in the tree cover, which include both loss and temporary changes, have amounted to over 28 million hectares.
The impact of these changes is far-reaching, affecting not just the environment but also the ecological balance and carbon sequestration capacity of the region. The trend of increasing wildfires and urban expansion continues to pose a challenge to the sustainability of the United States' forests and green spaces.
